Title: Fatal Error / Missing Style Sheet Last modified: March 15, 2024 --- # Fatal Error / Missing Style Sheet * [adnantuturan](https://wordpress.org/support/users/adnantuturan/) * (@adnantuturan) * [2 years, 2 months ago](https://wordpress.org/support/topic/fatal-error-missing-style-sheet/) * Hi, * Since OpeanExtra tried to automatically install a newer version (2.2.6.) our website isn’t functioning anymore. I went to the recovery mode and saw, that Ocean Extra had trouble updating and it gave me the following error code: * Ein Fehler vom Typ `E_ERROR` wurde in der Zeile `180` der Datei `/mnt/web207/ a2/78/512141178/htdocs/STRATO-apps/wordpress_01/app/wp-content/plugins/ocean- extra/includes/admin-bar/admin-bar.php` verursacht. Fehlermeldung: `Uncaught Error: Undefined constant "OCEANWP_THEME_VERSION" in /mnt/web207/a2/78/512141178/ htdocs/STRATO-apps/wordpress_01/app/wp-content/plugins/ocean-extra/includes/admin- bar/admin-bar.php:180 Stack trace: #0 /mnt/web207/a2/78/512141178/htdocs/STRATO- apps/wordpress_01/app/wp-includes/class-wp-hook.php(324): Ocean_Admin_Bar->enqueue_css()# 1 /mnt/web207/a2/78/512141178/htdocs/STRATO-apps/wordpress_01/app/wp-includes/ class-wp-hook.php(348): WP_Hook->apply_filters() #2 /mnt/web207/a2/78/512141178/ htdocs/STRATO-apps/wordpress_01/app/wp-includes/plugin.php(517): WP_Hook->do_action()# 3 /mnt/web207/a2/78/512141178/htdocs/STRATO-apps/wordpress_01/app/wp-admin/admin- header.php(118): do_action() #4 /mnt/web207/a2/78/512141178/htdocs/STRATO-apps/ wordpress_01/app/wp-admin/plugins.php(621): require_once('...') #5 {main} thrown` * Can anyone please help? Most of the solutions include deactivating the plugin to fix the problem, but the plug in is the theme of our website. So if i deactivate it, the whole website is gone. (just white screen) I updated, every other plug in and wordpress to the newest version.

Do the same for the theme. * To avoid similar issues in the future, it is advisable to turn off automatic plugin updates in WordPress and manually update them from the WP Dashboard > Update. Additionally, I suggest creating a staging website and updating everything there before updating your production website. This way, you can safely update all themes and plugins on your website. * Please recheck your issue and keep us posted. * I hope it helps.
